CHARLES J. SAGEBRECI-IT, OF TORONTO, ONTARIO, CANADA, ASSIGNOR- TO INTERSTATE ELECTRIC NOVELTY COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

To all "whom it may concern:

Be it known that I, Cnannes J. SAGE. nin zcn'r, a citizen of the United States of America, residing at Toronto, Province of Ontario, Dominion of Canada, have invented certain new and uset'ul Improvements in Electric Pocket Flash-Lights, of which the following is a full, clear, and exact description.

This invention relates to improvements in pocket flash-lights, but pertains more particularly to a. special means to prevent a short circuit from being established between the circuitcl0scr on the casing, and the lamp, through the reflector, the cap which retains the lens, and the sleeve which is engaged by the cap to hold the reflector and lamp in the casing.

I will now proceed to describe my inven tion in detail, the essential teaturesof which will be summarized in the appended claims, reference being had to the accompanying drawing, forming part hereof, wherein:

Figure 1 is a vertical sectional view of a pocket flash-light embodying my improvement; Fig. 'Z is a plan view of the flashlight, the reflector and lamp being removed; and Fig. 3 is a sectional view of the upper portion of a pocket flash-light, the lens bein removed, illustrating another embodiment of my invention.

in th accompanying drawing, the casing of a. pocket flashlight is indicated by 1, and contains the ordinary battery 2. lach end of the casing l is provided with the usual threaded sleeves 3 and lto receive caps 5 and (5 respectively. The cap 5 acts to hold I the lens 7 and reflector 9 with its lamp 9 in position, the lamp contacting with the carbon, pole 10 of the battery The cap 6 completes the circuit between the. con ductor 13 and battery 2 by means of the spring 11.

The circuit for the lamp 9 iscompleted bv means of the conductors l2 and 13 and circuit closer l t. The conductor 13 conveys the current to the circuit-closer H, and the conductor 12 conveys the current to the lamp by aid of special means. to be described, when the circuit-closer ll bridges the conductors 1:2 and 13.

The special means above referred to comprises an annular ring or bushing 15 (Fig. 1) located at the upper end 01 the bore of the casing 1, said bushing being of conductbpecification of Letters Patent. Patented June 13, 1916 Application filed January 31, 1916.

ing material and connected to the conduct mg strip 12. Current from the battery is conveyed to the lamp 5) by means of the strip 12, bushing; 15 connected thereto, and reflector 8 which contacts with the upper edge of said bushing. The reflector 8 is of course made of conducting material and is provided with a lamp-socket 16 to receive the lamp 9.

It is quite apparent that a circuit between the circuit-closer 14-. and cap 5 cannot be ell'ccted because the reflector, which is a part of the circuit, is out of contact with said cap, being kept out of contact therewith by the lens 7, which is of non-conducting material. Furthermore, the sleeve is not connected to any current carrying part of the device and is separated from the bushing 15 by the casing 1. The cap 6 is the only externally positioned or exposedcurrent carrying element. excepting the circuit-closer 141-, which is in circuit with said. cap 6.

When the circuit-closer is at ofl' position, it is impossible to complete the circuit for the lamp through any other exposed ele ments of the device.

Fig. 3 illustrates another embodiment of my invention. which comprises a. reflector 17 having a (lownwardly directed flange 18 which is connected to the conducting strip 12. la this latter form the reflector is not normally removable. In other respects the two devices are similar. I

Having now described my invention, what l claim and desire to secure by Letters Patent is:

1. In combination with the casing of a flashlight and the battery and lamp inclosed therein. a lens for said lamp, means for holding said lens in place, a conducting reflector in electrical connection with said lamp and held in place by said lens and said means, a conductor electrically connected to said reflector, a. bushing fitting the interior oi the forward end of the casing and in con tact. with said reflector and conductor. but insulated from said lens holding means, a second conductor electrically connected to the pole of the battery remote from the lamp and a circuit closing device movable at Will into position to'connect these conductors electrically together.

2. In combination with the insulating casing of a flash light and the battery and lamp i nclosed therein, a lens for said lamp, means for holding said lens in place. a conducting reflector in electrical connection with said lamp and held in place hy said lens and said means, a conductor electrically connected to said reflector, a bushing. fitting the inter or of the tm'irard end of the casing and in contact with said reflector and coiuluctor, hut insulated by said casing from said ineans, a second c mductor electrically connectl-al to the pole of the battery remote from the lamp, and a circuit closing device movable at will into position to connect these wnductors electrically together.

3. In combination with the insulating casing of a flash-light and the battery and lamp inolosed therein, a lens for said lamp, means for holding said lens in place, a conducting reflector in electrical connection with said lamp, a pair of electrical conductors having electrical connection respectively with said reflector and with the relnoter pole of said battery, a circuitclosing device arranged to connect the proximate ends of said (fondue tors, and a bushing fitting the inner face of the upper end of the said using and in contact with the reflector and the nearer one of said conductors, also msitively insulated from the lens holding means at all points by said casing and assisting the lens and said means to hold securely in place the said reflector, a part of the latter being clamped |)Q' tween the lens and this conductive device as shown.

Signed at Toronto, Canada, this 26 day of January 1916.
